Price does not always seem to be the main motivator for people to spend more. Be more enterprising – give your customers extra benefit(s) like free shipping or product, extra discount or anything else as soon as customer's current cart total reaches the amount required. Just set up the Shopping Cart Progress Bar Magento extension in a couple of clicks to make the eye-catching progress bar with special promo shown on the shopping cart page.
Our extension for Magento calculates how much more your customer should spend to get the benefit and shows the remaining amount via the progress bar widget. So customers have pure motivation to spend more to gain some extra profit.
For example, your customers get free shipping if their shopping cart subtotal is $100+. So when the cart total is $77, then the progress bar is 77% filled and shows that extra $23 should be spent for orders to be shipped for free. Quite a simple way to increase eCommerce average order value!
